First, off danke vielmals to Sulzer GmbH for providing conference facilities.

On Saturday, Sven C. Koehler gave a conference introduction talk, announced who was here and who might be speaking. Then each attendee gave their name and a brief explanation of how they came upon Ruby, and how they use it today. A rough schedule was then devised.

This was followed by a flawed, personal recollection of RubyConf 2004, by James Britt. Notable mostly for the ad hoc discussions on language design, the nature of object-orientation, hacking Ruby, the virtues of Javaipt, teaching/learning programming, RPA/Ruby Gems, and myriad other topics.

Next came Mathieu Bouchard talk on GridFlow and Ruby in electronic arts, about how Ruby is being used to help create art installations and performances. GridFlow is a tool for multidimensional array computation based on a dataflow computing paradigm, whose main purpose is handling live video transformations in an artistic context, and which is written in C++ and Ruby.

By then it was time to hop the U-Bahn and head out for dinner.

Sunday morning saw James Britt talk on ruby-doc.org; this time, the code demo actually worked. The talk gave an overview of how the site came to be, current issues, and beta code to make the site more usable.

Right now, Mathieu Bouchard is showing his reimplementation of Ruby’s Array/Hash/String classes in Ruby itself. It includes an explaination on how you can add a #undo method to an Array in about one page of Ruby code.

And lunch is being arranged at the back of the conference room.
